Paul Feig’s Ghostbusters (review) isn’t even out yet in the United States and already there is talk about a post-credits scene that hints at what may come in a future sequel.

Since there are going to be spoilers in this post, I’m going to write up the main facts and then embed a video. If you want to know what’s after the credits, you can scroll down. But don’t say I didn’t warn you!

The film, which comes out July 15th, stars Melissa McCarthy, Kristen Wiig, Kate McKinnon, and Leslie Jones. Director Feig has filmed cameos (in new roles) for many of the original Ghostbusters cast, including Bill Murray, Dan Aykroyd, Ernie Hudson, Annie Potts, and even Sigourney Weaver.

Andy Garcia, Michael Kenneth Williams, Matt Walsh, Neil Casey, and Pat Kiernan also star alongside Chris Hemsworth.

“SNL” vet Neil Casey is the main Ghostbusters villain, Rowan, and was described as a convicted murderer who turns into a ghost after his execution is hit by a supercharged electrical storm. This gives him the power to raise an army of other ghosts, which could be made up of famous villains throughout history.

Okay, now that all of that is out of the way, let’s talk about what happens in the post-credits scene, shall we?

Apparently Leslie Jones’ character Patty is listening to some equipment when she hears something that catches her attention. She turns to the other Ghostbusters and asks, “What’s Zuul?”

Zuul is the spirit that inhabited Weaver’s character Dana in the 1984 original Ghostbusters. Zuul is the minion of Gozer and is one half of the gatekeeper/key master duo.

Feig explained this little gag to IGN, “From the original movie Zuul is the bad guy who controls all the doings that go on. It’s such a great character we thought ‘well it would be fun if you could do a sequel,’ and who knows, to kind of have him in the mix?”

That being said, Feig is also very quick to explain that this doesn’t confirm a sequel NOR does it confirm that Zuul would be the villain in a second film. He’s simply saying that they’re open to the idea of another movie and the possibility of Zuul being a character at some point.

“We wanted to say possibly there’s something you know from the first one can come in. Again it’s not about creating the cinematic universe where suddenly there’s a worm-hole and the original Ghostbusters show up, although somebody might do that at some point. But I don’t know, it was kind of a little comfort food, easter egg, that gives us an opening if we wanted to do another movie.”

So, let’s not get ourselves worked up. This is simply a gag that is meant to pay homage to the original movie.
